目的:探讨下颌牙槽嵴低平患者全口义齿修复的改良设计方法及修复效果。方法:选取下颌牙槽嵴低平行全口义齿修复的患者68例,随机分为观察组与对照组,每组各34例。对照组采用常规方法行全口义齿修复,观察组行改良设计全口义齿修复。比较两组患者对外观、语音、固位性、稳定性、舒适程度的满意程度,评价咀嚼功能。结果:除外观外,观察组语音、固位性、稳定性、舒适程度均优于对照组,差异具有统计学意义(P<0.05或P<0.01)。观察组与对照组修复后咀嚼功能优良率分别为94.12%、79.41%,差异具有统计学意义(P<0.05)。结论:在常规全口义齿修复的基础上,对下颌牙槽嵴低平患者给予改良设计全口义齿修复取得了良好的效果,修复后具有较好的语音、固位性、稳定性、舒适程度以及咀嚼功能,对其临床治疗具有一定的指导借鉴意义。
Objective: To investigate the improved design and repair of complete denture in patients with mandibular alveolar ridge and flattened lower jaw. Methods: A total of 68 patients with mandibular alveolar crest low parallel total denture were randomly divided into observation group and control group, with 34 cases in each group. In the control group, the complete denture was repaired by the conventional method, while the observation group was treated with the modified denture. The two groups of patients were compared on the appearance, voice, retention, stability, comfort level of satisfaction, evaluation of chewing function. Results: In addition to the appearance, the observation group voice, retention, stability and comfort were better than the control group, the difference was statistically significant (P <0.05 or P <0.01). The excellent and good rates of chewing after the repair in the observation group and the control group were 94.12% and 79.41% respectively, the difference was statistically significant (P <0.05). Conclusion: Based on the conventional complete denture restoration, the improved complete denture repair in patients with mandibular alveolar crest has obtained good results. After the repair, it has good speech, retentivity, stability and comfort As well as masticatory function, have certain guidance and reference significance to its clinical treatment.
